Also, add some line and point features to the supermesh,
using the Add Lines and Add Points
tool. Finish a line with a double-click on the last node.
The polygons that we have created can be merged
with the Join Polygons option. First, both polygons
need to be selected. Activate the Select in
Rectangular Region tool in the Mesh-Editor
toolbar and click into both polygons while holding
. The selected polygons are now highlighted in
turquoise. Now the Join Polygons button in the
Mesh-Editor toolbar is activated. Click this button
to merge the two polygons.
Polygons, lines and points that have been misplaced
can also be deleted. Activate one of the selection tools
available in the drop-down list that opens with a click
on the small arrow next to Select in Rectangular
Region. Click on the merged polygon (if it is not still
selected). Then simply press the key to remove
the polygon. You may try the same with one or several
of the lines or points.

Polygon nodes can also be positioned exactly. In the
next step, we design a square polygon with the dimensions
of 100 m x 100 m. First, select all remaining
polygons, lines and points and press to delete
them. Next, click Add Polygons and press .
The Pin Coordinates toolbar appears. Insert
0,0 to set the first node and press . In the
same way, enter the coordinates of the remaining three
nodes of the polygon. To finish the polygon, enter the
coordinates of the first node again or simply click on it.
If one or several nodes are misplaced while a line
or a polygon is drawn, the last node(s) can be deleted
by clicking on a previous node of the same line or polygon.
